That was
an accepted notational practice at the time for appoggiaturas. There’s a pretty interesting discussion of this in the
New Grove Dictionary of Music and Musicians article on “Ornaments,” ยง 9.i.

Thanks, David and Federico — easy fix! All layout engines have their architectural weak spots, so that 's no surprise I guess.
I guess the rendering of that first sixteenth as a grace note in this piece is somewhat arbitrary anyway, since the first measure is always playes simply as four sixteenths.
Doubtless some historical reason.
Thanks again,

Hello all:
So I am trying to lay out the first bars of Mozart's Sonata K 333. The first measure is a partial measure. No matter what I try so far, I'm getting an extra time and
key signature in the bass clef, in addition to the bass clef first displaying as treble, then adding a bass clef in:
The code is as follows (I didn't see how to make it tinier):
\version "2.18.2"
\include "english.ly"
keyTime = { \key bf \major \time 4/4 }
upper = \relative c''' {
\partial 4 \grace g16 f8 ef16 d |
}
lower = {
\partial 4 r4 |
}
\score {
\new PianoStaff <<
\new Staff = "upper" { \clef "treble" \keyTime \upper }
\new Staff = "lower" { \clef "bass" \keyTime \lower }
>>
}
Any help appreciated :-)
Welcome to LilyPond!
Sorry you had to discover so quickly perhaps the most persistent bug in the program.
It's easily fixed, though: add a corresponding grace spacer to the other part at the same point.
\partial 4 \grace s16 r4
